I don't think so. The concept of having spare land, sure. Private ownership of land is and always has been a social construct, subject to limits imposed by both society and physics. To claim that it is "sacred" is to misunderstand the nature of society.
Accordingly, modern (sub)urban land ownership has very little to do with Spanish and English colonial land grants or US settlers. It comes with huge social benefits and is encumbered by extensive permitting, taxation, and use limits. You'll notice that Vinod Khosla isn't interested in exchanging his Half Moon Bay property for, say, an equivalent amount of land in North Dakota, where he might be permitted to block public access all day long.
